McCain and Kerry served together for decades in the U.S. Senate, and the Arizona lawmaker has often ribbed Kerry about his aspirations to become secretary of State. At a press conference in January, McCain said he planed to "mercilessly" question Kerry during his confirmation hearing.
“We will bring back, for the only time, waterboarding to get the truth out of him,” McCain said.
A month before, McCain jokingly introduced Kerry as the secretary of State before he had been nominated by President Obama. Kerry jabbed back, referring to McCain as "Mr. President" — a nod to McCain's failed 2008 presidential bid.
"See, this is what happens when you get two losers up here, folks," Kerry continued, acknowledging his own failed effort in 2004.
